CLAVIERS BAROQUES -- Helmholtz notation.

There have been various notation systems devised to specify the octave as well as the musical note when not using notes on a staff. Helmholtz notation, while confusing, is the scholarly standard and the method you will see most often to describe the compass of a harpsichord or the specify a string as well in medical or scientific discussions involving acoustics. Perhaps that will change, for example, the much more convenient American system is showing up on tuning meters these days, too, eg Korg.
